Django使用 Bootstrap 样式修改书籍列表过程解析

展示书籍列表：

首先修改原先的 book_list.html 的代码：

添加书籍：

再来修改 add_book.html

<!DOCTYPE html>

  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<!-- 以上 head 部分从 book_list.html 赋值过来并加以修改 -->

<!-- 以下 body 部分可从 Bootstrap 网站上找相关代码 -->
<body>

<div class="container">
  <div class="row">
    <div class="col-md-6 col-md-offset-3">

      <div class="panel panel-primary">
        <div class="panel-heading">添加书籍</div>
        <div class="panel-body">
          <form class="form-horizontal" action="/add_book/" method="post">
            <div class="form-group">
              <label for="book_title" class="col-sm-2 control-label">书名</label>
              <div class="col-sm-10">
                <input type="text" class="form-control" id="book_title" name="book_title"
                    placeholder="书名">
              </div>
            </div>
            <div class="form-group">
              <label for="inputPassword3" class="col-sm-2 control-label">出版社</label>
              <div class="col-sm-10">
                <select class="form-control" name="publisher">
                  {% for publisher in publisher_list %}
                    <option value="{{ publisher.id }}">{{ publisher.name }}</option>
                  {% endfor %}
                </select>
              </div>
            </div>
            <div class="form-group">
              <div class="col-sm-offset-2 col-sm-10">
                <button type="submit" class="btn btn-success">提交</button>
              </div>
            </div>
          </form>
        </div>
      </div>
    </div>
  </div>
</div>
</body>
</html>

修改过程：

先写一个 container

找一个面板，在 Bootstrap 的组件中可找到

复制代码，并进行修改

现在需要一个 form 表单，在 Bootstrap 的全局 CSS 样式中找

复制下面的代码，替换面板代码中的 Panel content，并进行修改

先修改 email 处

<div class="form-group">
  <label for="inputEmail3" class="col-sm-2 control-label">Email</label>
  <div class="col-sm-10">
    <input type="email" class="form-control" id="inputEmail3" placeholder="Email">
  </div>
</div>

修改为：

<div class="form-group">
  <label for="book_title" class="col-sm-2 control-label">书名</label>
  <div class="col-sm-10">
    <input type="text" class="form-control" id="book_title" name="book_title" placeholder="书名">
  </div>
</div>

再来修改 password 处，这里需要用到下拉列表，还是去 Bootstrap 上找

在 “菜单” -> "被支持的控件" 处

复制代码，并进行修改

<div class="form-group">
  <label for="inputPassword3" class="col-sm-2 control-label">Password</label>
  <div class="col-sm-10">
    <input type="password" class="form-control" id="inputPassword3" placeholder="Password">
  </div>
</div>

修改为：

<div class="form-group">
  <label for="inputPassword3" class="col-sm-2 control-label">出版社</label>
  <!-- 下拉列表 -->
  <div class="col-sm-10">
    <select class="form-control" name="publisher">
      {% for publisher in publisher_list %}
        <option value="{{ publisher.id }}">{{ publisher.name }}</option>
      {% endfor %}
    </select>
  </div>
</div>

接着修改剩下的部分

最后在 form 表单处添加 action 和 method

运行效果：

编辑书籍：

最后修改 edit_book.html

<!DOCTYPE html>

<html lang="zh-CN">

  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<body>

<div class="container">
  <div class="row">
    <div class="col-md-6 col-md-offset-3">

      <div class="panel panel-primary">
        <div class="panel-heading">编辑书籍</div>
        <div class="panel-body">
          <form class="form-horizontal" action="/edit_book/" method="post">
            <input type="text" style="display: none" name="id" value="{{ book_obj.id }}">
            <div class="form-group">

              <div class="col-sm-10">
                <input type="text" class="form-control" id="book_title" name="book_title"
                    placeholder="书名" value="{{ book_obj.title }}">
              </div>
            </div>
            <div class="form-group">
              <label for="inputPassword3" class="col-sm-2 control-label">出版社</label>
              <div class="col-sm-10">
                <select class="form-control" name="publisher">
                  {% for publisher in publisher_list %}
                    {# 通过 if 条件判断来选择默认出版社 #}
                    {% if book_obj.publisher_id == publisher.id %}
                      {# 默认选择当前书籍关联的出版社 #}
                      <option selected value="{{ publisher.id }}">{{ publisher.name }}</option>
                    {% else %}
                      {# 其他的出版社不选中 #}
                      <option value="{{ publisher.id }}">{{ publisher.name }}</option>
                    {% endif %}
                  {% endfor %}
                </select>
              </div>
            </div>
            <div class="form-group">
              <div class="col-sm-offset-2 col-sm-10">
                <button type="submit" class="btn btn-success">提交</button>
              </div>
            </div>
          </form>
        </div>
      </div>
    </div>
  </div>
</div>
</body>
</html>

修改过程：

首先把 add_book.html 复制过去，然后修改相关标题，把 “添加书籍” 改为 “编辑书籍”

然后在 form 表单下一行添加一个有书籍 id 的 input 标签

然后在书名的那个 input 处添加一个 value

然后将下拉列表的出版社选择改为原 edit_book.html 的
